  • Emulated legacy bus operation over a bit-serial bus
    Patent number: 9858235
    Abstract: Legacy bus operations, such as x86 I/O instructions having an address space separate from memory address space, are supported in a system in which I/O devices are coupled to a microcontroller connected via an SPI bus or other bit-serial bus. Each legacy bus operation is recognized and trapped by an interface controller, such as a south-bridge controller, which maps the trapped legacy bus operation into a corresponding bit-serial bus transaction, and transacts this corresponding bit-serial bus transaction on the bit-serial bus. Existing software infrastructure using x86 I/O instructions can remain intact, with I/O transactions bound for the SPI bus.

  • EMULATED KEYBOARD CONTROLLER AND EMBEDDED CONTROLLER INTERFACE VIA AN INTERCONNECT INTERFACE
    Publication number: 20140006645
    Abstract: A method for emulating a command for communication with an input/output (I/O) port includes receiving the command from a host and redirecting the command to a microcontroller, whereby the microcontroller emulates the command by communicating with the I/O port.
